face view of one of two mold jaws which I employ, and showing the methodof connecting the same with the framework of the machine, and; Fig. 7 aview similar to Fig. 6 but showing a modification.

In the practice of my invention I provide a furnace a composed in theform of construction shown of an outer metallic wall or casing (1*,having an inner lining a of fire brick or other suitable material, andthe furnace a is supported on legs a. Within and resting on the bottomof the furnace chamber a is a gas and air burner b, with whichisconnected a Bunsen burner device I) for supplying gas and air to saidburner, and it will be understood that the burner 17 may be of anydesired construction and any suitable means may be provided forsupplying the same with gas and air or other combustion medium.

The front wall of the furnace casing a extends upwardly only to thepoint a", and said furnace is open at the top, and set thereinto is amain melting pot a, the front wall 0 of which rests on the front wall ofthe furnace casing a at a and extends upwardly only to the point a. Themain melting potc is provided at the top with a flange which'rests on acorresponding flan e at the top of the furnace casing and the ack Wallof the main melting pot a is preferably set inwardly as shown at 0 andthis forms a downwardly directed extension 0 of said main melting pot; 7

Set into the main melting pot c is a sup plemental melting pot dProvided with a vertically arranged cylinder d and an n wardly andforwardly directed tubular d1scharge (i The supplemental melting pot a.is provided with a top plate (1 which rests on the main melting pot 0,and the front of the top plate (1 of the supplemental melting potd. iscut out to forma recess d throu h which the cylinder d opens upwardly. Te

supplemental melting pot d is provided witha front wall (i which extendsfrom top plate d of the supplemental meltingpot d and rearwardly of thecylinder (1 is a transverse plate e having a raised bracket consistingof a front member e and backwardly dinected parallel jaws e", and alever fis pivoted in the member e at f and which is free to'swingvertically between the jaws e and said arm is provided with a handle fMounted in the cylinder 03 is a piston 9 having a plunger rod 9 and alink member g is pivoted to the plunger rod 9 at g and in the lever f at9 and by means of the lever f which is manipulated by the handle f thepiston 9 may be raised or lowered as will be readily understood.

In the back side of the cylinder d and preferably midway thereof is alarge port or passage 9 through which, in the operation of the apparatusas hereinafter described, the' liquid or molten metal flows from themain melting pot a into the cylinder 0Z and supplemental melting pot d.

One wall of the furnace, preferably the back wall is provided with anopening 9" through which the burner b, or the condition of the furnacechamber may be examined, and by means of which or through which theburner may be ignited, and this opening may be closed in any desiredmanner when necessary or desirable; and at the top portion of said wallof the furnace is an escape flue or passage (i through which the hotgases of combustion may pass.-

At the front of the furnace is a frame it consisting of parallel sidebars if, the front ends of which are secured to the sides of the furnaceat h and the rear ends of which are connected by a cross bar it, andsaid frame is provided with legs it which correspond with the legs a",and the frame it in the form of construction shown is slightly inclineddownwardly and forwardly from the furnace.

Mounted on the front end portions of the side bars 72. of the frame h,are slides k which are made adjustable on said side bars if by means ofscrews h" passed therethrough and through the cross bar 723 of the frameh, and in the bottom of said slides below the side bars k is atransverse shaft 2', one end of which is provided with an arm '5 bywhich said shaft may be rotated, and said shaft is also provided betweenthe side bars k with forwardly directed arms i which are secured theretoand with which are connected links 2' which are also connected withslides 2' mounted on the side harsh and to which are connected orsecured supplemental side bars 71 which extend forwardly flush with theside bars k and to or approximately to the furnace a.

Mounted on. the'side bars k of the frame h, and between the frame andthe furnace a,are other slides 77 through which the supplemental sidebars 71 are movable, and in the bottom portions of the slides 2' ismounted a transverse shaft 7' provided at one end With an arm 7' bywhich it may be rotated. The shaft j is provided between the bars 5 witharms j which are rigidly secured the distance between the slides z" andi may be adjusted. Secured to the slides j at k is a yoke-shaped frame10 consisting of parallel side members .70 and a transverse portion is,and in .the position of the parts shown in Fig. 1, the transverseportion of the yoke-shaped frame 70 is directly over the shaft 3' andthe front end of said frame i rests on the slides 2' The yoke-shaped"framenk is shown detached in Fig. 4 and preferably consists of top andbot-tom members is and 7c separated by blocks as shown at is or in anydesired manner, and the transverse part 70 of said frame is provided onthe bottom thereof with a keeper 70 through which is passed a movableplate is, to the front end of which is secured a block m. The block mconsists of a vertically arranged .rear member m and forwardly directedarms m m and m", and the plate is is secured between the arms m and m ofsaid block, and a lever n is pivoted in one side of the yoke-shapedframe 7: at n and passes transversely across the frame h, and betweenthe top and bottom parts 70 and 70 of the yoke-shaped frame 70 and ispivoted between the arms m and m of the block on by means of a pin orbolt passed through a longitudinal slot formed therein as shown orindicated at a; and a supplemental block n is secured to the bottom ofthe block on, and by means thereof a cut-off plunger 0% is rotatablysecured to the block on at and in the manner shown at m in Figs. 1, 2, 3and 4.

A cross head 0 is secured to the rear ends of the supplemental side bars11, and two similar mold jaws p are provided, one of which is secured tothe cross head 0 and the other to the cross head j, this connectionbeing preferably made by screws as shown at 32 and said mold jawsrp andthe cross heads 5' and 0 are provided with a central transverse passagep and when these parts are in the position shown in Figs; 1 and 3, thepassage p through the mold jaws p' and cross heads 7" and 0 communicatewith the nozzle of of the discharge (i of the supplemental melting potd, and

the cut-off plunger m operates through the passage p and through thecross heads 7' radial passages r as clearly shown 1n Figs.

1, 2 and 3.

An annular water jacket is mounted on "the nozzle a! of the discharge (iof the supplemental melting pot d, and this water jacket is providedwithtubular connections 0 which serve as inlets and outlets for water,and in practice, or in the use of the machine as hereinafter describedWater may be constantly circulated through the water jacket 0* in orderto cool the nozzle d and the adjacent parts. i

The cross head 9' is provided centrally with a hub s in the form ofconstruction wardly, this operation being performed,

when desired by turning the shaftz'.

From the foregoing description it will be seen by moving the arm 1' ofthe shaft 2' forwardly the slides '71 and 77 and the supplemental sidebars 2' connected with said slides, together with the cross head 0, theshaft and cross head 7' together with the .mold aws p, the yoke-shapedframe k ,'and the parts m and 'n, by which the plunger cut-off m isoperated may allbe moved forwardly,and this will separate the cross head0 andthe mold jaw 2 connected therewith from the nozzle d, and if thewater jacket 0 be connected with the cross head 0 it will be separatedfrom said nozzle, butin the ordinary operation of the machine the aboveparts are moved, the cross head 0 with its mold jaw p, remainingstationary .or in the position shown in Figs. 1, 2 and 3. It will alsobe seen that with the parts in the position shown in Figs. 1 and 3 theshaft 7' may be rotated by turnin the arm j forwardly so as to move thesli es 7' together with the cross head ji, and the mold jaw 2 connectedtherewith into the position shown in Fig. 2 so as to separate the moldjaws p, and with the parts in the position shown in' Figs. 1 and 3 thearm n may be operated so as to move the cut-off plunger m into theposition shown in either of said figures.

This'machin'e is particularly designed for casting various articles fromwhat are known as soft or comparatively soft metal I be molded and fromwhich the castings are which will melt iron, and in practice the'metalor metals to to be made are placed in the main melting ,pot' 0 and theburner b is ignited. The

molten metal, as will be understood passes mto the cylinder (1 throughthe opening uicker than steel or cast ing 9. At this stage of theprocedure thecross head 0 and mold jaw 79- connected therewith being inthe position shown in Figs 1, 2 and 3, the cross head 9' and mold jaw pare also moved in theposition shown in said figures by means of the arm9' and there is a continuous passage from the dis charge d of the pot dinto the casting chamber or chambers 1". The piston g is then forceddownwardly by means of the arm 1 and the pressure of said piston on themolten metal in the pot d forces said metal up through the dischargedand through the nozzle 0Z and into the casting chambers 1* in the jawsp, and the said molten metal fills said chambers. The lever n is thenmoved backwardly and the cut-ofi plunger m is forced backwardly throughthe mold jaws p, and into and through the nozzle cl, and all surplusmolten metal is cut off and forced back through said parts, and into thedischarge d of the pot d and flows downwardly into said pot and thiskeeps all the molten metal in proper condition for a re-operation of theplunger 9 and'the making of new castings. At the .end of the abovedescribed operation the arm 7' of the shaft 7' is moved forwardly andthe cross head 7' ,and its-mold jaw p are moved into the position shownin Fig. 2, and the castings drop out of the casting chambers r and fallinto a suitable receptacle provided therefor, and this operation maybecontinued as long as desired or until it becomes necessary to again fillthe main melting pot 0 with metal.

It will be observed that the supplemental pot d is entirely within themain pot a as is also the discharge tube or passage (Z and with thisconstruction the molten metal in said parts is kept in proper conditionfor casting atall times and by reason of the operation of the cut-offplunger m as herein shown and described, all surplusage of metal at eachcasting operation is forced into the said discharge d and flows backdowninto the pot d and mingles with the body of molten metal therein. a

In Fig. 7 I have shown a modified form of the cross head 0 and amodified means for connecting it with the side bars if consisting .ofyoke-shaped keepers t formed on or connected with said cross head and inwhich the bars '5 are secured, and the bars it also pass through saidkeepers. Although I haveshown and described the cross heads 0 v and j,and the mold jaws p as formed separately and connected, it will beapparent that'this method of connecting said parts is not absolutelyessential, and said parts may be formed integrally if desired; andalthou h I have shown and described the main -meltmg pot' a andsupplemental pot d as formed separately it will also be apparent thatthis method of constructing said parts is not absolutely essential andsaid parts may be formed integrally if desired. The casting chambers 1'in the mold jaws p may also be made of any desired shape or formaccording to the design or configuration of the articles to be cast, andany desired number of said casting chambers may be employed as will bereadily understood.

The side of the yoke-shaped frame k to which the lever 11. is pivoted asshown at n is provided with a plurality of apertures t whereby thepivotal point of said lever may be adjusted forwardly or backwardly asmay be desired so as to regulate the operation of the plunger cut-ofi' mIt will also be understood that the adjustment of the shafts i and jforwardly and backwardly on the frame h facilitates the operation of theapparatus and the movement of the cross heads 0 and j may be regulatedas may be desired. My invention is also not limited to the particularmeans herein shown and described for supporting the cross head 0 and itsmold jaw p, and these parts may be supported in connection with thenozzle 03 in any desired manner and I prefer to support the said crosshead and its mold jaw 19 in connection with the nozzle d so that saidparts can be moved toward and from said nozzle.

The movable mold jaws, the devices for operating said jaws, the plunger,and means for operating said plunger, and the framework in which saiddevices and means are sup orted, are not claimed herein but are ma e thesubject of a divisional application filed January 3, 1911, Serial No.600,390.
